| Summary: | The possibility of acoustic wave propagation in optical waveguides creates new
prospects for simultaneous transmission of laser beams and ultrasonic waves. Combined
laser-ultrasonic technology could be useful in e.g. surgical treatment. The article
presents the results of experimental studies of transmission of ultrasonic wave
in optical fibres, the core of which is doped by 7.5% of TiO2, using a sandwichtype
transducer. It also presents amplitude characteristics of an ultrasonic signal
propagated in the optical fibre. Authors studied the effect which the length of the
fibre has on the achieved output signal amplitudes. They presented the relation of
the output signal amplitude from a capacitive sensor to the power applied to the
sandwich-type transducer. The obtained results were compared with the results produced
when using an optical fibre with a core doped by 3% of GeO2, in order to
select optical fibre suitable for simultaneous transmission of ultrasonic waves and
laser rays. |
